Threats
This is the public information directory of the web, much like a phone book or Google Maps.
What is DNS?
An application installed on a PC a user would employ to compose, send, and view received mail. It uses traditional email protocols.
What is an Email Client?
This operates based on community collaboration to establish blacklists, as well as heuristic analysis.
What is Anti-Spam?
This Knowledge Base article details the process by which a Western NRG Engineer installs HES for a customer, from start to finish.
What is the SonicWall Hosted Email Security (HES) Project Playbook?
The act of pretending to be someone or something you are not.
This server answers client queries with record information.
What is a DNS Resolver
This is a protocol used to send mail. It has secure (SSL/TLS) variants.
What is Simple Mail Transfer Protocol (SMTP)?
Offering Zero-Day Threat Protection, this security service scans file attachments up to 100 MB in size.
What is Capture Advanced Threat Protection (CATP) for Email Security?
Because we must edit its DNS records to install HES, we require the customer have their own.
What is a Domain?
The act of tricking a person into doing something they normally would not do.
What is Phishing?
These act as the post offices of the web, exchanging emails between one another to deliver email from sender to recipient.
What are Mail Transfer Agents (MTAs)?
To determine what server or servers on the web are hosting any particular domain's mail, this type of DNS record would be queried for.
What is a Mail Exchange (MX) record?
This open-source security mechanism defines what servers on the web are authorized to send mail on behalf of a given domain.
What is Sender Policy Framework (SPF)?
These are the three items to address in a HES Kickoff Call.
What are a) gather information, b) set expectations, and c) prepare for installation.
A non-technical concept that exists outside the digital world, this can be irreparably harmed by email-borne threats.
What is reputation?
This particular DNS Resolver acts as the primary source of record information for a domain. The domain administrator can edit record information on this server.
What is the Authoritative Name Server?
A web interface that allows users to compose, send, and view received mail. It uses HTTP or HTTPS, hopefully the latter.
What is Webmail?
This security feature scans links within emails on traversal, but also rewrites the links so that they will be redirected and scanned a second time should the recipient user click on them.
What is Time of Click (ToC)?
Prior to implementing outbound mail filtering, Western NRG will edit this to ensure mail is not interrupted. If this does not exist, we will help create it.
What is an SPF record?
An ideal tool in a malicious actor's arsenal, this can be leveraged to send virus-laden emails to recipients that would be very trusting of the emails' source.
What is a compromised email address?
These act as middlemen between the consumer and ICANN, leasing or selling domains and almost always hosting the customer's Authoritative Name Server.
What are Registrars?
On receiving an email from an unfamiliar server, the recipient MTA would perform this kind of anti-spoofing check against the sending MTA's IP address based on the "From" domain in the email.
What is an SPF (Sender Policy Framework) check?
While this function cannot protect your email accounts from being compromised, it can prevent compromised email accounts from damaging your reputation.
What is Outbound Filtering?
After successfully implementing inbound and outbound mail Filtering, Western NRG will also help with this to better protect the customer.
What is hardening the mail host?
